HiFonics ZXS8D2

The HiFonics ZXS8D2 from the ZEUS STREET series is a powerful 20 cm (8-inch) subwoofer designed specifically for punchy bass reproduction in compact enclosures. With a 300-watt RMS power handling capacity and a 2+2-ohm dual voice coil, it offers versatile connection options and is suitable for both sealed enclosures and bass-reflex designs.

The hand-formed paper cone features a special coating that ensures high stability. Together with the double-stitched surround, it can withstand even heavy mechanical stress at high bass levels.

A dual-magnet system with a pole-piece bore and additional ventilation channels provides powerful drive. The generously sized 50-mm voice coil, the robust steel basket, and the blue magnet protector round out the high-quality design.

Thanks to its compact design, the ZXS8D2 can be used even in very small enclosed enclosures. Alternatively, a properly tuned bass-reflex enclosure enables particularly dynamic and deep bass reproduction.
